Be patient with your smaller seedweight plants I have seen no evidence of genetic inferiority based on seedling size at germination---yet.

So if you have multiple plants it's probably good to compare growth rate and health as they begin to vine if possible. Although my plants in this experiment were confined to their original seedling tray, they did eventually vine out, and then I began to notice differences. As they began to vine out to 3-5 developed leaves, the health and growth of the plant stop correlating to the seedweight. With everything environmentally the same, growth @ 3-5 developed true leaves presumably begins to show genetics. This will take maybe six or eight weeks.
